The Effect of Supplementing Air-Dried Moringa stenopetala Leaf to Natural Grass Hay on Feed Intake and Growth Performances of Arsi-Bale Goats

Abstract:The most constraining factor in goat production in the tropics is underfeeding mainly attributed to limitations of feed both in quantity and quality. This study was conducted to assess the effect of supplementing different levels of air-dried Moringa stenopetala leaf (MSL) as a protein source on nutrient intake and growth performances of Arsi-Bale male goats. A total of 24 yearling goats with average initial body weight of 13.6 ± 0.25 kg were used in the study. The goats were blocked by live weight into four groups (n = 6 per group) and the groups were then randomly allocated into four supplemented treatments. All goats received a basal diet of natural grass hay ad libitum and 340 g/head/day concentrate. The treatments were the control diet with no supplementation (Treatment 1, T1) and diets supplemented with MSL at a rate of 120 g/head/day (Treatment 2, T2), 170 g/head/day (Treatment 3, T3) and 220 g/head/day (Treatment 4, T4). The duration of the experiment was 75 days. The results indicated that the average daily feed intake was (p < 0.001) higher in goats supplemented with T3 and T4 diets. The total dry matter, organic matter, and crude protein intakes of goats fed with T3 and T4 supplementations were (p < 0.001) also higher than those reared in T1 and T2 diets. Goats reared in T3 and T4 diets had lower (p < 0.05) feed conversion ratio than those fed with T1 and T2 diets. The final body weight in goats reared in T3 and T4 diets was 18.2 kg and 18.5 kg, respectively, being (p < 0.05) higher than those of T1 (15.8 kg) and T2 (16.3 kg). The average daily weight gain in goats fed with T3 OPEN ACCESSAgriculture 2015, 5 1184 and T4 diets was 111 and 114 g/goat/day, respectively, which was (p < 0.05) higher than those reared in the control (T1) (54.0 g/goat/day) and T2 (58.1 g/goat/day) diets. It can thus be concluded that goats reared at high level of MSL supplementation (T3 and T4) had better nutrient intake, feed conversion efficiency and growth performances, suggesting its potential as a good protein supplement to natural grass hay at the farmer's management level.

“…These countries have shown harsh tropical environmental conditions, where goats, in particular, express great adaptability (Galal, 2005). Furthermore, there is general and common agreement that domesticated animals descended from a single ancestor, originating in Asia.…”

“…However, goat breeds have recently faced major threats to their genetic diversity, which has resulted from systemic drought and unplanned crossbreeding with other native or exotic goats. Limited information is available on the molecular genetic diversity structure and relatedness of goats in Arab countries (Galal, 2005). Even though it is widely accepted that domesticated goats of this region are the most closely related to their common ancestors (Piper and Ruvinsky, 1997), there is no published reports stating so using molecular DNA markers.…”

ABSTRACT.The present study aimed to analyze genetic relatedness and differentiation of common native goat populations in some countries of the Middle East. The populations were Ardi, Black Bedouin, and Damascus goats in the Kingdom of Saudi Arabia, Jordan, and Syria, respectively. Domesticated goats of the Middle East are mostly related to common ancestors, but there is limited molecular genetic evidence. Four microsatellite DNA markers were genotyped in 89 individuals of the three populations using an automated genetic analyzer. Ardi, Black Bedouin, and Damascus goats exhibited high average allele number and expected heterozygosity of 8.25, 9, and 7.25, and 0.750, 0.804, and 0.779, respectively. F-statistics for population differentiation showed 6.0% of total genetic variation, whereas 94.0% as differentiation between individuals within all populations. The least varied within populations was Ardi goats, then Damascus goats and finally Black Bedouin goats. Furthermore, the Damascus goat population was more differentiated from Black Bedouin goats than from Ardi goats. On the other hand, there was strong evidence of admixture between the majority of Ardi and Black Bedouin goat individuals but little with those of Damascus Goat genetic relatedness and phylogeny goats. Genetic distance between Ardi and Black Bedouin goats was the shortest, whereas it was the longest between Ardi and Damascus goats. The phylogenetic tree clearly revealed the expected degree of differentiation in the three populations. From a genetic conservation point of view, it is recommended to maintain the biodiversity of these distinct populations in case genetic migration of genetic resources and genetic conservation are absent.

“…These breeds or types were distributed across the world as a result of the migration and translocation of humans, usually due to changing climatic conditions and natural resources. The world goat population now consists of an enormous amount of genetic variation in morphological and production characteristics (Galal, 2005;Shrestha et al, 2005). According to the Food and Agriculture Organization of the United Nations (FAO, 1999), there are now about 570 breeds of goats in the goat database.…”
